Ontraport Enhanced Ecommerce – Update existing orders

Update the Enhanced Ecommerce integration for Ontraport (https://wpfusion.com/documentation/ecommerce-tracking/ontraport-ecommerce/) to allow syncing order edits (such as changed products or line items) to the existing order in the CRM, instead of creating a new order. Also, (if possible) make it so that when an order status is changed from Refunded or Canceled back to Completed, the order is un-refunded in Ontraport. (the Mark As Paid endpoint may work for this https://api.ontraport.com/doc/#mark-transaction-as-paid )
